EDITED PHOTOS - does it save to your account?

Hi there,

I have come to the understanding that I am not on top of my backing up of photos game. 😞

My phone got stolen & I have lost enourmouse amount of pictures taken over the last 2 years.

Now in the recovery process I was hoping that my edited pictures would be attached to my light room account, I do have the paid subscription. 

However after logging in, I discovered I was mistaken. 

1)

How does it work to back up file with light room, is there a way to access previous edited / uploaded content. 

2)

& then how is the best way to go about preserving pictures, I dont love the cloud - but are starting to feel like that's the only option ?

All school hard drive backups, obviously only work when you religiously get to them.

Hope you'll have some insight:)
